Heatmiser Slimline RF Wireless Thermostat – White 230v

Slimline-RF V3 transmits heating demand wirelessly to a compatible Heatmiser receiver, so no mains or switching cable is required at the thermostat position. It is suitable for rooms where installing new control cabling would be difficult or disruptive. For multi-zone underfloor heating, the thermostat can be paired with the UH8-RF V2 eight-zone wiring centre. It can also work with the Heatmiser RF Receiver Switch for smaller heating systems. The thermostat can operate in non-programmable, 5/2-day, full 7-day or 24-hour modes. Programmable operation provides four adjustable heating levels each day, allowing different temperatures to be scheduled around normal occupancy. Optimum start calculates how early the heating needs to operate to reach the selected temperature at the programmed time. Further functions include temporary temperature hold, holiday mode, frost protection, adjustable switching differential and keypad locking. Slimline-RF V3 can be configured for heating only or combined heating and hot-water operation when paired with a suitable receiver and system arrangement. Combined mode provides four programmable hot-water switching periods per day alongside the room-heating schedule. The thermostat does not offer a separate timer-only mode. Hot-water switching must be used as part of the combined heating and hot-water configuration. The thermostat includes a built-in room-air sensor and can also operate from a compatible wired remote air sensor. This allows the temperature to be measured away from the thermostat where its mounting position is not representative of normal room conditions. Slimline-RF V3 does not support floor-sensor control or floor-temperature limiting. A remote sensor is not supplied with the thermostat and must be selected separately where required. The thermostat is powered by two AAA batteries, which are supplied with the unit. Rechargeable batteries must not be used. A low-battery indicator is displayed when replacement is required. Slimline-RF V3 is designed for surface mounting and measures approximately 85mm x 98mm x 24mm. When replacing the batteries, the new batteries should be inserted within one minute to retain the current clock and programme settings. Slimline-RF V3 provides local wireless heating control but cannot pair with the Heatmiser neoHub and does not support neoApp control. Where wireless app-based control is required, consider the Heatmiser neoAir V3 Wireless Thermostat.
